Well, whatever the reason, it's time to embrace it -- beauty trends for the upcoming autumn months are all about going plummy with your eyes, lips, and cheeks for a sultry yet sophisticated seasonal look. But before you raise an eyebrow at the thought of your grandmother's purple eyeshadow, you should know that these products are anything but retro-tacky! Update a smoky eye with a color-coordinated Stila eyeshadow quad in Montemarte, finished off with Urban Decay's Ink For Eyes in Empire. The contrasting color works wonders in bringing out the gold flecks in your eyes.
